title: Monosodium glutamate is related to a higher increase in blood pressure over 5 years: findings from the Jiangsu Nutrition Study of Chinese adults.
abstract: OBJECTIVE
  One large cross-sectional study across four countries suggests that glutamate intake may be inversely associated with blood pressure (BP). The aim of this analysis was to investigate a possible association between monosodium glutamate (MSG) intake and change in blood pressure over 5 years.
  
  
  METHODS
  Data from 1227 Chinese men and women who participated in the Jiangsu Nutrition Study (JIN) were analyzed. In this study, MSG intake and blood pressure were quantitatively assessed in 2002, and followed-up in 2007.
  
  
  RESULTS
  MSG intake was associated with a significant increase in SBP and DBP. A strong sex interaction was observed in relation to SBP change. Women with high MSG intake were more likely to have increased SBP and DBP. Total glutamate intake was also positively associated with an increase in SBP. In those chronically taking antihypertensive medications, there was a strong association between MSG intake and an increase in DBP.
  
  
  CONCLUSIONS
  MSG intake may have independent BP-increasing effects, especially among women and those taking hypertension medications at baseline and follow-up.
